The upload web page doesn't verify the file type, and an attacker can upload a webshell by making a fileUpload.shtml request for a custom .shtml file, which is interpreted by the Apache HTTP Server mod_include module with \"<!--#exec cmd=\" support. The file needs to include a specific string to meet the internal system architecture. After the webshell upload, an attacker can use the webshell to perform remote code execution such as running a system command (ls, ping, cat /etc/passwd, etc.). NOTE: the vendor reportedly indicates that this is an intended feature or functionality","published":"2018-04-01T18:29:00.000Z","lastModified":"2026-06-17T02:06:11.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-434"],"affected":["axis/m1033-w firmware"],"epss":{"score":0.03109,"percentile":0.8772,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (3.11%).
